This is a template you can use to report issues. You can also drag images, videos and include `Preformatted text`

## Expected behavior

We are upgraded to typescript recently with instructions:  
[https://docs.forestadmin.com/woodshop/how-tos/translate-your-app-into-typescript](https://docs.forestadmin.com/woodshop/how-tos/translate-your-app-into-typescript)  
dist folder is created properly, all files are compiled but we have:

1. SyntaxError in terminal and
2. Broken application.

## Actual behavior

Hello @Bojan_Antonijevic,

I have been able to reproduce your exact issue.

Could you move the `interfaces` folder one step above and rewrite the imports in `routes` and `models` files.  
It should remove the:  
`Cannot find module '/Users/bojanantonijevic/Desktop/web-app/forest-admin/dist/models/interfaces'` error.

Also could you modify the file `models/index.js`:  
And replace line 27:

```javascript
.filter(function (file) {
    return file.indexOf('.') !== 0 && file !== 'index.js';
  })

```

by

```javascript
.filter(function (file) {
    return file.indexOf('.') !== 0 && file !== 'index.js' && file.indexOf('.js.map') === -1;
  })

```

It should remove the `SyntaxError: Unexpected token ':'` errors.

We will update the documentation for fixing this issue too.

Tell me if it helps 😃

Thank you @Guillaume_Cisco,

Solutions from your reply fix the issues.

One more thing. Do you have any logs on your side regarding these errors from the console:

You’re welcome @Bojan_Antonijevic.  
I’m glad it helped you.

Does your server correctly run on localhost with port `3310`?  
I can see from your previous logs it seems to run on `3000` .

Could you check your configuration, especially regarding ports.

Let me know if it helps 😉

Thank you once more 🙂. That solves our ERR\_CONNECTION\_REFUSED problems.

But we have one more.  
On any collection, we get 500 with the message:

```javascript
{"errors":[{"status":500,"detail":"connect ETIMEDOUT"}]}

```

Console errors:

Do you have a clue?
